Downloaded GFS data unable to get executaed by ungrib.exe

Dear all,

I have been experiencing this problem for a while. I have downloaded the GFS data from https://nomads.ncep.noaa.gov/pub/data/n ... 6/00/atmos for 24 hours starting from gfs.t00z.pgrb2.0p50.f000 to gfs.t00z.pgrb2.0p50.f024 . But when I am executing it using ungrib.exe it shows

Looking for data at time 2021-03-26_00

ERROR: Data not found: 2021-03-26_09:00:00.0000

I have tried it running it for 12 hours too. But the same error is coming every time. I am attaching namelist.wps and namelist.input. I'll be highly obliged of getting help from your end.

This is because you don't have the GFS data at 2021-03-26_09:00:00.00

Please take a look at your GRIB file, and make sure the GFS file at the above time does exist in your working directory.
